Pore Size - an overview ScienceDirect Topics

Pore sizes greater than 50 μm facilitate the growth of new bones into these holes [34]. The minimum pore size required for the framework is 80–100 μm for osteoconduction [35]. The mechanical properties often decline with the increase of porosity [34]. Therefore, the framework is usually prepared to jointly consider these two factors.

Water-filled pore space and porosity: If 60 percent or more of the pore space is filled with water, important soil processes are impacted. Soil respiration and nitrogen cycling (ammonification and nitrification) increase as soil moisture increases (fig. 5). In dry soils, the rate of these processes decreases because of a lack of moisture.
